No, my bad for not noticing what forum topic we were in.

By the time I finished reading the message, it had scrolled off the screen and the version didn't show in your screenshot.
The reason I asked is that there was a bug in an earlier version that prevented them from showing. Maybe it's back.
OTOH, did you maybe put them in protected resource groups that you don't have access to? If you connect a resource group to a user group that you are not a member of, you hide resources from yourself. One solution is to add yourself to all user groups with a role of Super User.
Thanks for buying the book.
